REVERSIBLE FOLDiNG-SASH WINDOW.

Specification of Letters Patent.

Patented Feb. 26, 1.907.

Application filed July 12. 1906- Serial No. 325,891.

To all whom it ntay concern;

when open and in a regular position is accessible for cleaning on both sides to a person standing inside of the window-opening; sec- 0nd, to provide a window wherein nearly the entire area ,or a desired fraction thereof, may be opened, so constituted that the sashes during ordinary wind force will remain in whatever position placed without slamming or movement of any kind, except by direct human interference, and, third, to provide a window with sashes that may be readily forced into proper position durim the closing rior locking device.

of the window if the material of the sashes or frame is swelled. or otherwise varyin from proper shape. I attain these objects %y the arran ement of frame, sashes, and mechanism ifiustrated in the accompanying drawin s, in whichigure 1 is an exterior view of the entire Window, showing same artly open. Fig. 2 is a horizontal section sowin the position of sashes in the frame when t-ie window is closed. The dotted lines show different 'positions of the sashes when the window is open. Fig. 3 is a horizontal section through one side of sash and frame, showing a top view of the ty e of hinge adaptable for releasing the sash 120m either side of the frame, as may be desired. Fig. 4 is a vertical section through the top or lintel of the window, showing a groove in the frame and a uidein in sash, also a side view of the top hinge.

ig. 5 is a vertical section through'the bottom or sill of the window, showing a groove in the sill, a guide-pin in the bottom of the sash, a side view of the bottom hinge, and an inte- Fig. 6 is an exterior view of one lower corner of the frame and sash, showing front view of the bottom hin e and indicating manner ofraising the pin 1n the knuckle of the hinge, so as to release the sash from the side stile of the frame when so desired.

I leased from the frame.

Similar letters refer to similar parts throughout the several views.

The sashes A, which must be in one or more pairs, are hinged to the stiles B of the frame on a special type of hinges E, adapted to be released on either side of the window, as may be desired, by turning the handle Lon the inner side of the sash and penetrating directly through the sash and carrying the curved plate K or a cog arrangement of similar principle, thereby raising the pin in the knuckle of the hinge until the sash is rerequired for access to the outer side of both sashes for cleaning from the position of a person standing on the inner side of the window. In special cases where the access to the outer side of both sashes in the manner and for the purpose heretofore described is not considered of special value a simpler method may be adopted-c 6., the hinging of one sash only to the corresponding stile of the frame, using any adaptable type of hinge now in public use, but otherwise arranging the sashes and frame substantially as shown.

The meeting stiles of the sashes must be hinged together, substantially as indicated on the drawings, by means of any adaptable type of hin es now in public use.

The lintel C andsill D have grooves, as indicated at I, to engage the guide-pins G of the sashes in order to maintain that edge of the sash which is not secured by hinges in proper position when the window is open. The holes H in sill D are for the purpose of draining away any water that may lodge in the groove To adjust the sash, it is required to force the edge of the one sash which is released from the hinges or themeeting-stiles, or both, in desired direction.

On the inner side, secured to the bottom of one of the meeting-stiles of one sash, a looking device is. provided, the handle M being adapted to swing around and engage the fixed catch N on the'sill or stool of the window, the handle M being also adapted as means of pulling -or forcing'the sash into proper position. A hook and e e or any other adaptaole device now in public use may be adopted in place of the special locking device shown and described.

The window is so constructed as to be opened by the act of swinging or forcing the sashes in outward direction.

This arrangement is I am aware that prior to my invention windows have been made with a pair of of the window, and pro'jectionsat the outer corners'o'f thesashes, fitting into grooves in the sill and lintel of the frame, for maintaining the detached edge of either sash in the same vertical plane with the edge which remains hinged to the frame.

In a window the combinationof apair of sashes hinged to fold one upon the other and ,a detachable pivoting device at fixed Eoints or axes near both the vertical joints etweenthesashes and the frame, adapted to syvinlg;zor adjust the two combined sashes from either pivoting point or axis as may be desired,in conjunction with projections near the outer corners of the sashes, fitting into a groove in .either the sill or the lintel of the frame, adapted to form a slidingconnection between the detached edge of either'sash and the frame, for maintaining said detached edge in the same vertical plane with theedge which remains attached to the corresponding side of the frame by means of the pivotmg device.

joining edges and also connected to the frame at both the opposite edges by means of a detachable pivoting device adapted to release either sash from the corresponding side of the frame, so that the one sash thus released may be folded upon the one sash attached to the frame when said attached sash is swung or pivoted until the window is fully o ened, and a sliding connection between t e detached edge of either sash and the frame, for maintaining said detached edge in the same vertical plane with the. edge which remains connected to ,theframe by meansof the piv oting device. o

4. In a window, the combination of a pair of sashesrattached together by means of ,a

hinge connection, and detachable pivotal ,connections to the frame near the four corners or angles of the window-,afiolding a 'fixed pivoting oint or axis at both the oppositeedges of t e combined sashes, adapted to transfer the combined weight of thepair of sashes ,to one or the other pivotal axis as maybe desired in opening and closing the window, and an adjustable connection between the sashes and the frame, adapted to maintain the detached edge of either sash inthe same vertical plane with the edge which .ELWYN *E.
